Abstract
The preparation of CuO nanoparticles with a mean primary particle size of 21 nm is described, using commercially available precursors. A key component of the method is sonochemical energy input. The overall method is energy-efficient with minimal waste and is therefore ecology (biosphere)-preserving. In liquid suspension the particles from agglomerates with a mean size of c. 500 nm.
